In obese individuals, dysfunctional adipocytes secrete proinflammatory cytokines, such as tumor necrosis factor-alpha (TNF-α) and interleukin-6 (IL-6), as well as chemokines, especially CCL2, which plays a major role in recruiting immune cells to ATs, resulting in obesity-associated metabolic inflammation [14]. This evidence concerns the gene CCL2 and obesity disorder.
